Abstract — Coffee is one of mainstay plantation 
commodities in Humbang Hasundutan Regency and as a 
source of countries income, providers of employment, and 
encourages the development of agribusiness and 
agroindustry. Lintong Ni Huta is one of coffee production 
center in Humbang Hasundutan Regency that famous 
with Coffee Lintong. The purpose of this study was to 
determine the suitability of the land and to identify the 
production of coffee types at various altitudes in Lintong 
Ni Huta. The results of agriculture coffee plantation and 
production In Lintongnihuta is the largest and most 
located in the villages in the altitude of 1400-1500 meters 
mean abaut sea level and the altitude of coffee planting in 
Lintongnihuta regency does not affect coffee production. 
Keywords — Lintong Coffee Production, Altitudes Place. 

I. INTRODUCTION 

Coffee is a plantation crop that has long been cultivated, 
as well as a source of income not less than one and a half 
million peasants in Indonesia, coffee is also a commodity 
mainstay of exports and sources of foreign exchange 
income of the country. Indonesia's coffee now judging by 
the results, the fourth rank largest in the world. Coffee has 
a long history and has an important role for economic 
growth in Indonesia. Coffee (Coffea sp) Can contribute 
11% of the total export of Indonesian plantation crops. 
Estimated area of coffee plantation exploitation in 
Indonesia about 1,227,787 ha with production of 637,539 
tons. North Sumatera as one of the largest coffee 
plantation area after South Sumatera, Lampung, Aceh and 
East Java with coffee plantation area of 81,474 ha with 
production of 60,307 tons (Directorate General of 
Plantation, 2017). Coffee is one of the mainstay of 
plantation commodities in Humbang Hasundutan 
Regency and has a role as a source of income of foreign 
countries,and sources of income, providers of 
employment, and encourage the development of 
agribusiness and agro-industry. Lintong Ni Huta is a 
coffee production center in Humbang Hasundutan 
regency famous for its Lintong Coffee. Coffee plantation 
area in this regency with 9.246 Ha harvested area and 


6,461 tons production. Coffee plantations comprise 
48.45% of the area of agricultural land and plantations. 
(Humbahas In Figures, 2011) the development of coffee 
cultivation requires shade plants as a protective against 
direct sunlight to reduce the evapotranspiration process. 
Rainfall and temperature are climate factors that affect 
coffee production. In this case the volume and distribution 
of rainfall throughout the year, and the altitude of the 
place determines the suitability of growing coffee plants 
(Rothfos, 1980). The annual rainfall required for Arabica 
coffee growth ranges from 1,100-1,300 mm and for 
Robusta coffee is 1,550-2,000 mm. Distribution of 
rainfall is very effected in determining the pattern of 
plant fertilization because it is associated with the process 
of breaking the dormancy of interest. While the height of 
the appropriate place for the growth of Arabica coffee is 
1000-2000m above sea level, whose temperature 
conditions range from 15 0C to 24 OC, and for the 
Robusta coffee <700 MASL. whose temperature 
conditions range from 24 OC-30 OC (Wilson, 

1985).Several factors affecting production and quality, 
especially on organoleptic characteristics, have not been 
scientifically identified, need further research to identify 
those prioritized factors. Organoleptic characteristic is an 
advantage for coffee type. The height of place, the type of 
soil, the climatic conditions such as temperature, 
humidity, until processing, storage, and marketing 
techniques need to be tested in relation to the quantity and 
quality of coffee production. 

n. LITERATURE REVIEW 
Cultivation of Coffee Crops 

Economically, the growth and production of coffee plants 
is highly dependent on or affected by climate and soil 
conditions. Another basic requirement that can not be 
ignored is looking for superior seeds whose production is 
high and resistant to pests and diseases. After these 
requirements can be met, an important thing is 
maintenance, such as: fertilization, pruning, shade trees, 
and the eradication of pests and diseases

Varieties Coffee Sigarar Vtang 

This coffee is a type of arabica coffee that thrives in 
mountainous areas with an altitude of 700-1700m above 
sea level. This type of coffee is very suitable to be grown 
in cold climates such as in Tapanuli. Sigarar coffee plants 
have semi-dyed stature, short branch segments, a lush 
canopy covering the entire surface of the tree so that the 
trunk is not visible from the outside. The nature of the 
secondary branching is very active even the primary 
branch above the ground surface forming a dangling fan 
touching the ground. The old leaves are dark green, the 
young leaves (flush) are brown. When planted without 
leafless leaf shelves and leaf blades panting, when viewed 
at a glance the shape of long tapered leaves and edges of 
wavy leaves. Young fruit is green while the ripe fruit is 
bright red, round long elongated round fruit shape and 
100 ripe fruit (red) on average - 196 gr. Production 
potential ranges from 800 to 2300 kg of seed / ha. Sigarar 
type coffee from debt is somewhat susceptible to leaf rust 
disease, especially grows at an altitude of less than 1000 
MASL, is also susceptible to nematode parasites 
(Panggabean E, 2011) 

Soil and Climate suitable for coffee growth 
Coffee will grow if plant growth requirement can be 
fulfilled that is soil with effective deep enough (> 100 
cm), slack, well drained, and enough water, enough 
nutrition, especially potassium (K), enough organic, 
material 3%). The ideal soil acidity (pH) for coffee plant 
growth ranges from 5.3 to 6.5. As long as this coffee is 
commonly grown in Indonesia there are two types of 
Robusta and arabica. Both types of coffee physiologically 
require requirements of different climatic conditions. 
Arabica coffee requires higher land than Robusta coffee, 
because it is grown in wetlands besides growth and 
productivity it is more susceptible to leaf rust disease. 
Arabica coffee with some criteria of planting place: High 
700-1400 MASL, daily air temperature 15-24 celcius, 
average rainfall 2.000-4.000 mm / years, dry month 1-3 
month / year, acidity level (pH) soil 5.3 - 6, organic 
matter content> 3%, soil effective depth> 100 cm, 
maximum slope of 40%. Arabica coffee cultivation close 
to sea level is infected with leaf rust disease. Medium at 
an altitude of more than 2,000 m is often disturbed with 
dew upas. (Panggabean E, 2011). Coffee is affected by 
extreme season conditions, where prolonged dry seasons 
or excessive rain disturb flowering and fertilization. 
Conditions of high rainfall will disrupt the process of 
pollination of coffee flowers assisted by wind pollinators 
and beetles. Before the bloom, the physiological flowers 
of coffee will have a period of dormancy. At that time the 
flower buds stopped its development for several months 
(1-4 months). Factor is development of interest after the 


dormancy period is the availability of ground water. 
Although the dormancy period has passed but if the 
groundwater is not sufficient to the needs of division 
process lowers then the flowers will not bloom. The 
flowering process is usually triggered by the arrival of the 
rainy season or through the watering process (Cannell, 
1985). 

Growing Terms 

Coffee plants have special properties because each 
species needs a slightly different environment. 
Environmental factors that greatly affect the growth of 
coffee plants, among others, the height of the place, 
rainfall, sunlight, wind, and soil (Najiyati, 2004). 

A. Place Height 

The actual height of the place does not directly affect the 
growth of the coffee plant. Air temperature factors have a 
direct effect on the growth of coffee plants, especially the 
formation of flowers and fruits and sensitivity to disease 
attacks. In general, high temperatures are affected by the 
altitude of the sea surface. 

b. Rainfall 

Rain is the most important climate factor after the height 
of the place. This factor can be seen from rainfall and 
rainfall time. Rainfall will affect the availability of water 
needed by plants. 

c. Sun 

In general, coffee does not like a lot of direct sunlight, but 
it requires sunlight that spreads / spreads. Large direct 
sunlight increases evaporation of soil and leaves, thus 
disrupting the balance of photosynthesis, especially in the 
dry season. In addition to its effect on photosynthesis, 
sunlight also affects the process of flower bud formation. 
A lot of sunlight will stimulate the formation of flower 
buds. Thus, if coffee plants throughout the year produce 
continuous direct sunlight then the plants will form 
flowers throughout the year. 

As a result the flowering becomes irregular and the plant 
produces flowers beyond its ability so that the number of 
successful flowers becomes a bit of fruit. 

To arrange the arrival of sunlight, usually among coffee 
plants grow shade plants. This shade factory is set so that 
coffee plants can grow in the shade and get enough 
sunlight. 

d. Wind 

The role of the wind is to help move the pollen from one 
plant to another with different clones. Thus, pollination 
occurs that can produce fruit. In addition to the positive 
effects on coffee plants, sometimes the wind also has a

negative effect, especially during high winds. Strong 
winds will directly damage the plant canopy or abort the 
flowers. Strong winds that come in the dry season will 
also accelerate the occurrence of evapotranspiration 
(evaporation of water from plants and soil) resulting in 
drought. 

e. Soil 

In general, coffee plants require loose soil, fertile, and 
rich in organic matter. Therefore, the soil around the plant 
should often be given organic fertilizer to be fertile and 
loose so that the root system grows well. In addition to 
loose soil and rich in organic matter, coffee also requires 
a bit of acid soil, which is between pH 4.5 to 6.5 for 
robusta coffee and pH 5-6,5 for arabica coffee. If the soil 
pH is less than that amount then the coffee plant can still 
grow, but less able to absorb some nutrients so the land 
needs to be chalked. On the other hand, the coffee plant 
does not want a slightly alkaline soil (pH above 6.5) so 
that lime is not excessive (Panggabean E, 2011) 

III. METHODOLOGY 

The research was conducted in Lintong Ni Huta in 
various altitudes. The altitudes of the study sites ranged 
from 1200 MASL to altitude> 1500 MASL divided into 
several groups of places as follows: 1200 - 1300 MASL, 
1300 - 1400 MASL, 1400 - 1500 MASL and > 1500 
MASL. The research method is used field research that is 
descriptive analysis both quantitative and qualitative, the 
research based on solving factual problem that exist at 
this time. The collected data is arranged, explained, and 
then analyzed. Data used in this research are climate data 


(rainfall), area and productivity of coffee plant. This data 
was obtained by citing data and reports from related 
offices (Office of Statistics and Dishutbun Kabupaten 
Humbang) and taken directly from farmers as samples. 

Interview 

Structured interviews were conducted using 
questionnaires with coffee farmers. The contents of the 
questionnaire on research related issues are plant age, 
area, type of coffee grown, plant height, number of stems 
of tree, number of branches of tree, number of coffee 
beans tree branch, coffee production. 

IV. RESULT AND DISCUSSION 

Growth and Production The average coffee at an altitude 
of 1200 - 1500 meters above sea level in Kecamatan 
Lintongnihuta shows not significant difference where the 
height of the growing place is still in accordance with the 
need to grow arabica coffee plants. From the results of 
interviews with farmers (figure 1) shows that at an 
altitude of 1400 -1500 MASL obtained growth and better 
coffee production, this is possible because at the sunlight 
received by plants enough for photosynthesis activity and 
cloudy air conditions serve as a shade that prevents 
excessive sunlight from that received by coffee plants due 
to the coffee plant will produce large amounts of 
continuous interest in full sun exposure is also required to 
balance carbohydrate production to keep the fruit load as 
presented by DaMatta (2004) the coffee plant can become 
regarded as a species with widespread plasticity in 
response to various radiations

Results of Fanner Questionnaire 

Farmers are still conventional and farming traditional 
coffee by letting coffee grow as it is. Pruning the coffee 
plant is still a strange thing, which is done only on plants 
that are not productive growth. It is necessary to change 
the habit and understand the usefulness of pruning as one 
part of care to maintain the balance of plant development 
in order to produce optimal fruit production. 
To get high quality results, the coffee picked after 
cooking is the time of red fruit skin. For arabica coffee 
the time required from flower bud formation until ready 
to be harvested is 6 - 8 month. The average harvest data 
was obtained in June 2016, at the time of flowering 
around November-December 2015 where the number of 
rainy days is quite high (Table. 4) thus affecting the 
formation of the yielded interest slightly affecting the 
crop average% compared to last year, which decreased by 
20% to 30%. The resulting flower remains on the fruit 
stalk although at the time of fruit enlargement, except at 
altitude> 1500 MASL there is a new flower on the fruit 
stalk. This happens because the sunlight that continues to 
stimulate flowering. Higher fruit loads reduce seed size 
due to competition between carbohydrates during filling 
fruits. These results can be offset by agricultural 
management such as fertilization, tree pruning to help 
farmers improve the sustainability of coffee plantations, 
produce higher quality seeds and higher and ultimately 
increase their income. (Vaast, P, et al 2006) The altitude 
of the place correlates with the temperature, precipitation 
and soil organic matter. In relation to this condition, the 
higher the cultivation area, the lower the temperature and 
the higher the organic matter. The taste of Arabica coffee 
is getting better as the place grows. This condition is 
related to the temperature at the flowering period, the 
filling of the fruit, and the ripening of the fruit. This is 
expected to affect the taste of Arabica coffee. The higher 
the place also looks the better the physical quality of 
coffee beans indicated by the low percentage of black 
seeds, pests and disabilities. (Karim, A, Hifnalisa, 
2012).Climate also has a big effect on coffee plant 
productivity. Climate effects begin to emerge from the 
main branch before flowering. And this continues to be 
felt at the opening of flowers until the path of pollination, 
the growth of young fruit grow old and ripe fruit, in 


coffee plants. Toward the dry season the weather 
generally starts to clear, the air is never cloudy. Because 
the rain has begun to fall, it means the solar radiation will 
be more and more, then the temperature will also 
increase. Primary branches (plagiotropes) of growing 
flowers begin to prepare for growth. Therefore, the more 
radiation, the preparation of the formation of flowers on 
coffee trees will be faster. Conversely, if irradiation 
decreases, preparation is slow and the amount of interest 
in the preparation of coffee trees is also low (Beer, J, et 
al., 1998) From previous research, it was found that the 
production to taste of coffee is determined by the way of 
processing, varieties, and height of the planting place 
(Mawardi, et al., 2008; Karim and Hifnalisa, 2011). 

Coffee Cultivation in Kecamatan Lintongnihuta 
The condition of coffee planting in several villages in 
Lintongnihuta with different height levels in Table 3 is 
seen at an altitude of 1200-1300 meters above sea level, 
only Sitio II village with planting area around 104 ha with 
coffee production of 60.48 tons. Area and production is 
lower than coffee plant in other villages such as 1,300- 
1400 bowls with the best coffee production of 117.48 tons 
from planting area of 202 ha, Siponjot village, the 
altitudes 1400-1500 masl is Tapian Nauli village with 
Production at most 131.43 ton is generated from 226 ha of 
coffee planting area and> 1500 masl altitude there is 
112.82 tons of coffee production from 194 ha planting 
area of Dolok Margu village. The average coffee 
production for Kecamatan Lintongnihuta was 0.58 ton / 
ha. From 22 villages in Kecamatan Lintongnihuta 12 
villages are located at an altitude of 1400-1500 masl with 
coffee cultivation area of 1570 ha, 8 villages are located 
at an altitude of 1300-1400 masl with an area of 885 ha of 
coffee and each 1 village is at an altitude of 1200 - 1300 
masl with coffee planting area of 104 ha and in altitude> 
1500 masl there are 104 ha. The largest coffee cultivation 
area compared to the villages in Siponjot and Sibuntuon 
Partur, about 30% of the total area is coffee cultivation. 
Arabica Coffee Types of Sigararutang from Kecamatan 
Lintongnihuta have a very prominent role as a source of 
community income, employment and foreign exchange.

V. CONCLUSION 

Identification of coffee production In Lintongnihuta 
District is the largest and most located in the villages in 
altitude of 1,400-1500 meters above sea level. And the 
high coffee plantation in Kecamatan Lintongnihuta does 
not affect the production of coffee.
